Dings hazardous location brakes are UL listed and CSA certified
for use in atmospheres containing explosive vapors and materials. Every
model meets the requirements of both Class I Groups C and D and Class II Groups
E, F, and G.
Important Note: If a hazardous location brake is purchased
by other than an authorized electric motor manufacturer, a foot mounting bracket
must also be purchased to obtain the UL Label.
Thermal Overload Mechanism
When the external surface of the brake approaches the specified temperature
limit, the thermal overload mechanism will automatically release the brake and
hold it in the released position. This mechanism prevents the surface temperature
from rising to a level that could ignite surrounding gases or dusts by releasing
the brake and thereby stopping a further increase in temperature.
CAUTION: Once the brake has been released by the thermal
overload mechanism, control over the rotation of the motor and movement of the
load is lost. This uncontrolled rotation of the motor and movement of the
load could cause injury to personnel and damage to property.
Thermal Switch
The brake is also equipped with a thermal switch. When properly wired into
the motor starting circuit, the thermal switch shuts down the motor before the
thermal overload mechanism releases the brake. When the thermal switch
activates, it stops the motor and load, preventing the uncontrolled motion described
in the "caution" above.
